[0005] Patent Document 1: Japanese Patent Application Publication No. 2023-092312 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, in conventional riding-type rice transplanters, when the seedling loading platform is in use, the footrest for the rider to sit on the base plate overlaps with the seedling loading platform when viewed from above (see Patent Document 1). Figure 2 There are situations where it is difficult to use the pedals to get onto the floor.

[0008] The purpose of this invention is to provide a riding-type rice transplanter that allows the user to easily ride on the base plate when the seedling loading platform is in use.

[0009] Solution for solving the problem

[0010] The riding-type rice transplanter of the present invention comprises: a traveling body; a driver's unit disposed on the traveling body and having a floor for walking; a pre-seedling platform located on the lateral side of the traveling body, which can be switched between a working state and a folded state, wherein the working state is a state in which the pre-seedling platform is extended in the front-rear direction, and the folded state is a state in which the pre-seedling platform is shorter in the front-rear direction compared to the working state; a first step pedal disposed at a position forward of the rear end of the pre-seedling platform in the working state, for a passenger to alight and land on the floor; and a second step pedal disposed at a position rear of the first step pedal, for a passenger to alight and land on the floor.

[0011] According to the present invention, the structure includes not only a first step located forward of the rear end of the pre-planted seedling platform in its operational state, but also a second step located rearward of the first step. With this structure, even when the pre-planted seedling platform is in its operational state, the passenger can easily avoid the platform by using the second step when alighting from or landing on the floor. As a result, the passenger can easily alight from or land on the floor.

[0012] In this invention, it is preferred that a horizontal guard is provided, the horizontal guard being arranged to extend upward from the lower part of the vehicle body, the upper part of the horizontal guard being located behind the pre-planting platform, and the horizontal guard having a second pedal.

[0013] According to this structure, the following configuration is achieved: In addition to the first step, a second step is provided on the upper part of the horizontal guardrail located behind the seedling placement platform, allowing a passenger to alight and land on the base plate. This configuration allows the second step to be positioned corresponding to the rear part of the seedling placement platform, enabling the passenger to alight and land on the base plate by using the second step to avoid the seedling placement platform.

[0014] In this invention, it is preferred that the second pedal is located below the end portion of the pre-seedling placement platform in the front-rear direction during the use state.

[0015] According to this structure, passengers can more easily avoid the pre-planted seedling platform and more easily board and alight from the base.

[0016] In this invention, preferably, the outer end of the second pedal in the left-right direction is located laterally to the outer side than the left-right end of the prepared seedling platform.

[0017] According to this structure, the second step is located laterally outward from the seedling platform. Riders can more easily alight and land on the base using the portion of the second step located laterally outward from the seedling platform.

[0018] In this invention, preferably, the base plate has a first base plate and a second base plate, the second base plate is located behind the first base plate and is located above the height position of the first base plate, and the second pedal is located at a height position between the height position of the first base plate and the height position of the second base plate.

[0019] According to this structure, since the pedal is positioned at a height between the height of the first base plate and the height of the second base plate, a passenger who places their foot on the second pedal can easily board or alight from either the first or the second base plate.

[0020] In this invention, preferably, the base plate has a first base plate and a second base plate, the second base plate is located behind the first base plate and is located above the height of the first base plate, the first pedal is provided below the first base plate, and an extended base plate, which is separate from the second base plate, is provided on the lateral side of the second base plate, and the second pedal is located between the first pedal and the extended base plate in the front-back direction.

[0021] According to this structure, the second step is located between the first step and the extended floor, allowing the passenger to easily step onto the extended floor and easily get on and off the floor.

[0022] In this invention, preferably, the second pedal is configured to extend inward from the horizontal protective member in the left-right direction.

[0023] This structure positions the second pedal further inward in the left-right direction than the lateral guard. As a result, it prevents the pedal from damaging crops in the field during operation.

[0024] In this invention, it is preferred that a reinforcing member is provided, which is arranged across the inner end of the second pedal in the left-right direction and the horizontal protective member.

[0025] According to this structure, the second pedal can be more securely fixed to the horizontal guard. Attached Figure Description

[0039] Below the lateral side of the first base plate 12A, there is a step 33 for passengers to alight and land on the base plate 12. The step 33 has a support portion 33a that is U-shaped when viewed from the side and a step body 33b (corresponding to the "first step" of the present invention) provided on the bottom edge of the U-shaped support portion 33a. The upper part of the support portion 33a is fixed to the front support portion 31, and the support portion 33a is configured to tilt laterally outward as it moves downward. The step body 33b is formed of a plate-like member and is configured to allow passengers to step down when alighting or landing.

[0040] [Regarding the structure of the horizontal and rear protective components]

[0041] On both sides of the driver's compartment 13, horizontal guardrails 40 are provided, extending upwards from the lower part of the vehicle body 3. The left and right horizontal guardrails 40 are formed by bending round tubes into an inverted U-shape when viewed from the side. The lower end of the front longitudinal extension 41 of the horizontal guardrail 40 on the front side is fixed to the front support 31. The lower end of the rear longitudinal extension 42 of the horizontal guardrail 40 on the rear side is fixed to the rear support 32.

[0042] The front longitudinal extension 41 is formed in an inclined shape that is more forward as it moves downward. The upper front longitudinal extension 41a, which constitutes the upper part of the front longitudinal extension 41, is formed to be more inclined than the lower front longitudinal extension 41b, which constitutes the lower part of the front longitudinal extension 41.

[0043] A front transverse extension 43 extending inward in the left-right direction is formed at the lower end of the front longitudinal extension 41 (lower front longitudinal extension 41b). The left-right inner ends of the front transverse extension 43 are fixed to the front support 31.

[0044] The lower end of the rear longitudinal extension 42 has a rear transverse extension 44 that extends inward in the left and right direction. The left and right inner ends of the rear transverse extension 44 are fixed to the rear support 32.

[0045] A rear protective member 45 is connected to the rear longitudinal extension 42. The rear protective member 45 is arranged in the manner of a horizontal protective member 40 spanning the left and right sides, protecting the fertilizer applicator 7 from the rear. The rear protective member 45 consists of two horizontal frames 45A that form a U-shape when viewed from above, and four longitudinal frames 45B arranged in the manner of spanning the two horizontal frames 45A.

[0046] An extension support member 46 is fixed on the inner side of the horizontal protective member 40 in the left and right directions, which supports the extension base plate 12C from below.

[0047] [Regarding the structure of the pre-planted seedling platform]

[0048] like Figure 1 and Figure 2As shown, multiple seedling placement platforms 20 are arranged on the upper right and left sides of the vehicle body 3. These seedling placement platforms 20 can hold seedlings that have been rolled into rollers and secured by ropes, straps, etc. The multiple seedling placement platforms 20 are fixed to the vehicle body 3, supported by a pair of front and rear pillars 15 extending in the vertical direction, and located on the lateral side of the vehicle body 3.

[0049] The support pillar 15 is erected upwards from the portion of the vehicle body 3 that is forward of the front wheel 1. The rear support pillar 15 is erected upwards from the portion of the vehicle body 3 that is above the front wheel 1.

[0050] like Figure 2 and Figure 3 As shown, in the base plate 12 (first base plate 12A), the engine hood 11 and the plurality of seedling placement platforms 20 on the right side, and the engine hood 11 and the plurality of seedling placement platforms 20 on the left side form right and left passageways. Passengers can move from the vehicle body 3 to the field ridge through the right or left passageways, or enter the vehicle body 3 from the field ridge.

[0051] As multiple seedling placement platforms 20, it includes three first seedling placement platforms 20A, second seedling placement platforms 20B and third seedling placement platforms 20C located at the bottom, and a fourth seedling placement platform 20D located at the top.

[0052] The second pre-planted seedling platform 20B is fixed to the support column 15. For example... Figure 1 and Figure 2 As shown, the first pre-seeded seedling platform 20A is rotatably supported on the front end of the second pre-seeded seedling platform 20B via a folding mechanism 21. The third pre-seeded seedling platform 20C is rotatably supported on the rear end of the second pre-seeded seedling platform 20B via a folding mechanism 22. According to this structure, the first pre-seeded seedling platform 20A and the third pre-seeded seedling platform 20C are respectively configured to switch between a usable state and a folded state. The usable state is... Figure 1 The solid line in the middle shows the state in which the first pre-seedling carrier platform 20A and the third pre-seedling carrier platform 20C extend in the front-back direction to accommodate seedlings. This folded state is... Figure 1 The double-dotted line indicates that the first seedling support platform 20A and the third seedling support platform 20C are shorter in the front-to-back direction compared to the used state. That is to say, the first seedling support platform 20A, the second seedling support platform 20B, and the third seedling support platform 20C are configured to be switchable between the used state and the folded state (equivalent to the "seedling support platform" of the present invention).

[0053] like Figure 1 and Figure 2As shown, in the first pre-planting seedling platform 20A, in its operational state, the front end of the first pre-planting seedling platform 20A is positioned further forward than the front end of the engine hood 11 and the front end of the first base plate 12A, which constitutes the front portion of the base plate 12. In its operational state, the third pre-planting seedling platform 20C is located on the two lateral sides of the first base plate 12A, covering the platform body 33b of the boarding / alighting step 33 from above. It should be noted that the platform body 33b is positioned further forward than the rear end of the third pre-planting seedling platform 20C in its operational state.

[0054] The fourth pre-planting seedling platform 20D is fixed to the support column 15 above the second pre-planting seedling platform 20B.

[0055] It should be noted that a support member 16 is connected to the upper part of the support column 15, spanning the upper part of the support column 15 on the right and left sides.

[0056] [Regarding the structure of the auxiliary riding pedal]

[0057] like Figure 1 and Figure 2 As shown, the left and right horizontal protective members 40 are respectively equipped with auxiliary boarding steps 50 (equivalent to the "second boarding step" of the present invention) for passengers to sit and alight on the floor 12. Figures 2 to 4 As shown, the auxiliary boarding step 50 is composed of a plate-like member, which is fixed to the lower front longitudinal extension 41b of the transverse guard 40 on its left and right outer sides, and is configured to extend from the transverse guard 40 (lower front longitudinal extension 41b) toward the left and right inner sides. It should be noted that... Figure 3 and Figure 4 The structure of the auxiliary riding pedal 50 on the left is shown, while the auxiliary riding pedal 50 on the right has the same structure.

[0058] like Figure 1 and Figure 2 As shown, the auxiliary boarding footrest 50 is located further rearward than the rear end of the third pre-planting seedling platform 20C in its operational state. Figure 3 and Figure 4 As shown, a reinforcing member 51 is provided on the inner side of the auxiliary riding pedal 50 in the left and right directions, which is provided across the inner end of the auxiliary riding pedal 50 in the left and right directions and the front horizontal extension 43 of the horizontal guard 40.

[0059] Here, as Figure 1 and Figure 2 As shown, the upper part of the horizontal protective component 40 is located behind the third preparatory seedling platform 20C, and passengers can use this part as a handrail.

[0060] like Figure 1As shown, the auxiliary riding pedal 50 is located at a height position between the height position of the first base plate 12A and the height position of the second base plate 12B.

[0061] like Figure 2 As shown, the auxiliary seating platform 50 and the third pre-planting seedling platform 20C in use are configured to partially overlap when viewed from above. More specifically, as... Figure 1 and Figure 2 As shown, the auxiliary boarding foot pedal 50 is located below the end portion of the third pre-planting seedling platform 20C in the front-rear direction when in use.

[0062] like Figure 2 and Figure 3 As shown, the outermost end of the auxiliary boarding footrest 50 in the left-right direction is located laterally outward than the outermost end of the third pre-planting seedling platform 20C in the use state. Furthermore, as... Figure 2 As shown, the auxiliary boarding step 50 is located in the front-to-back direction between the boarding body 33b of the boarding step 33 and the extended base plate 12C.

[0063] Based on these structures, even when the third seedling platform 20C is in use and thus covers the platform body 33b of the boarding and alighting platform 33 from above, a portion of the auxiliary boarding platform 50 will not overlap with the third seedling platform 20C when viewed from above. Therefore, even when the third seedling platform 20C is in use, passengers can easily board and alight from the floor 12 using the auxiliary boarding platform 50.

[0064] [Other Implementation Methods]

[0065] The following examples illustrate other embodiments that modify the above embodiments.

[0066] (1) The auxiliary boarding pedal 50 can also be configured to rotate in the forward and backward directions. In this case, it can also be configured as follows: when the third seedling platform 20C is in use, the third seedling platform 20C is set to extend forward by rotating the auxiliary boarding pedal 50 in the forward direction; when the third seedling platform 20C is in the folded state, the third seedling platform 20C is set to extend backward by rotating the auxiliary boarding pedal 50 in the backward direction, and the passenger rides on the base plate 12.

[0067] Furthermore, the auxiliary boarding platform 50 can also be configured to be retractable and switch between an extended state (extended in the front-rear direction) and a shortened state (other than the extended state). In this case, it can also be configured such that when the third pre-planted seedling platform 20C is in use, the passenger uses the extended auxiliary boarding platform 50 to board and alight on the base plate 12; and when the third pre-planted seedling platform 20C is in a folded state, the passenger uses the shortened auxiliary boarding platform 50 to board and alight on the base plate 12.

[0068] (2) In the above embodiment, the structure of the auxiliary riding pedal 50 being located laterally to the outer side of the left and right direction is described as an example. However, the present invention is not limited to the above embodiment. It can also be set as follows: the front end of the auxiliary riding pedal 50 is located to the rear of the rear end of the seedling platform 20, and the seedling platform 20C and the auxiliary riding pedal 50 do not overlap when viewed from above.

[0069] (3) In the above embodiment, the structure of the auxiliary riding pedal 50 being located at a height position between the height position of the first base plate 12A and the height position of the second base plate 12B is described as an example. However, the present invention is not limited to the above embodiment. It can also be configured such that the auxiliary riding pedal 50 is located at a position lower than the height position of the first base plate 12A, or the auxiliary riding pedal 50 is located at a position higher than the height position of the second base plate 12B.

[0070] (4) In the above embodiment, the structure with the extended base plate 12C is described as an example, but the present invention is not limited to the above embodiment and may also be configured to not have the extended base plate 12C.

[0071] (5) In the above embodiment, the auxiliary riding pedal 50 is described as an example of a structure in which it extends from the horizontal guard 40 toward the inner side in the left and right direction. However, the present invention is not limited to the above embodiment. For example, the auxiliary riding pedal 50 may also be configured to extend from the horizontal guard 40 toward the front or rear in the front-back direction.

[0072] (6) In the above embodiment, the structure having the reinforcing member 51 was described as an example, but the present invention is not limited to the above embodiment, and may also be configured to have a structure without the reinforcing member 51. In addition, it may be configured to have a structure having multiple support members supporting the auxiliary riding pedal 50 from below instead of the reinforcing member 51.

[0073] (7) In the above embodiment, the structure in which the left and right horizontal guard members 40 are respectively provided with auxiliary riding pedals 50 is described as an example. However, the present invention is not limited to the above embodiment. It may also be provided that either the left or right horizontal guard members 40 is provided with an auxiliary riding pedal 50.

[0074] (8) It can also be configured as follows: multiple ribs are provided on either or both of the pedal body 33b and the auxiliary riding pedal 50, and reinforcement is provided by the multiple ribs.

[0075] (9) It can also be configured as follows: anti-slip protrusions are formed on the upper surface of either or both of the pedal body 33b and the auxiliary riding pedal 50.

[0076] It should be noted that the structures disclosed in the above embodiments (including other embodiments, the same below) can be combined with structures disclosed in other embodiments as long as they do not create contradictions. Furthermore, the embodiments disclosed in this specification are illustrative, and the embodiments of the present invention are not limited thereto, and can be appropriately modified within the scope of the purpose of the present invention.
